Category	Groundwater modelling
Publisher	Hemker, C J
Platform	Win95/98, WinNT, Win2000, WinXP, Vista, Windows 7
Status	Freeware
Description	MicroFEM is a program for groundwater modeling covering the generation of a finite-element grid through the stages of preprocessing, calculation, postprocessing, graphical interpretation and plotting. Confined, semi-confined, phreatic, and leaky multi-aquifer systems can be simulated. Modeling features: Saturated single-density flow; Multiple-aquifer systems; Confined, leaky and unconfined conditions; Heterogeneous aquifers and aquitards; Steady-state and transient flow; Spatially varying anisotropic aquifers; Spatially and temporally varying wells and boundary conditions; Precipitation, evaporation, drain, river and wadi top systems. Input & Output: Model files in ASCII format; DXF maps and flowline files import; Screen resolution output to printer; Plots of grids, contours, flowlines and time series; Surfer, Excel, and ArcView compatible data files; HPGL and DXF files export. Program features: Mesh generators for regional flow models and for civil engineering models; Interactive mesh design and adjustment; Graphical user interface and data base; Interactive assignment of spatially varying properties; Up to 2500 nodes per layer; User-assigned names for all nodes; Flow vectors and flowlines, 3-D particle tracking; Water balances for each aquifer, subarea and time step; Transient flow modeling in batch mode. 3D-model viewer; Automated parameter estimation (calibration). MicroFEM users manual and MicroFEM tutorial available.
